This third-person horror story takes place 300 years after the present day. You need to play as Jacob Lee, who, by the will of fate, ended up in the Black Iron prison: a maximum security institution on Callisto, a satellite of Jupiter. The prisoners began to turn into monsters, and chaos ensued in the prison. To survive, Jacob must fight his way to safety and escape from Black Iron, while uncovering the dark secrets buried beneath Callisto´s surface.


The Callisto Protocol is a fresh take on survival horror from Glen Schofield. Through atmosphere, tension, brutality, and terrifying moments of helplessness and humanity, The Callisto Protocol immerses players in an adrenaline-pumping story where unimaginable horrors lurk around every corner.


The Callisto Protocol takes place on the moon Callisto in the year 2320, and you play as Jacob Lee, an inmate of the Black Iron prison. A strange disease throws the prison into chaos, and Jacob must face his greatest fears to defeat the bloodthirsty creatures hunting him, while also uncovering the dark secrets of the powerful United Jupiter company.


In The Callisto Protocol, you need to master both hand-to-hand combat and shooting, including the unique gravity weapon used by the Black Iron guards to control prisoners. Players will have to get close to grotesque opponents, chop off their limbs, shoot off their legs and use everything at hand in order to survive each deadly battle.


Callisto is one of the most hostile and isolated moons in the universe, and it weighs heavily on Jacob as he tries to escape. You need to fight not only the monsters in Black Iron, but also the age-old secrets that abound both on the surface of Jupiter’s dead moon and beneath it.
